If 58 g of CaCO3 decomposes to form 24 g of CaO, what is the percent yield of CaO?
1. Write the equation.
CaCO3 ==> CO2 + CaO
2. Calculate the theoretical yield. Here is a solved example. Just follow the steps. http://www.jiskha.com/science/chemistry/stoichiometry.html
3. Calculate %yield, also given in the solved example.
